Description MSD8728 by MSD IGNITION – SOFT TOUCH REV CONTROL The Soft Touch Rev Control, PN 8728, is designed to be used on standard points ignition or inductive ignition systems. This means that the PN 8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems or even with an MSD 5 or Blaster Ignition (non-CD ignitions). The RPM Limiter is adjusted with plug-in modules and is supplied with 6,000, 7,000 and 8,000 rpm modules. When the engine reaches your set rpm, the Soft Touch circuitry kicks in and drops the spark to certain cylinders. This rpm limiter produces very accurate and smooth, backfire-free rev limits. Can be used on 4, 6 or 8-cylinder engines with inductive ignitions Adjusted with plug-in modules Includes 6,000, 7,000 and 8,000 rpm modules No MSD ignition control box required
